赤泥综合利用评述
|
摘要
赤泥是氧化铝生产过程中产生的固体废渣,目前的处置方式主要以堆存为主,大量赤泥的堆存已造成严重污染。论文通过对赤泥种类及化学组成的介绍,综述了赤泥在提取有价金属、制备新型建材及环保领域的综合利用研究进展。由于赤泥产量大,实现赤泥综合利用的产业化是今后的主要研究方向。
Red mud is a solid waste produced in the production of alumina. At present, the main disposal method is stacking. A large number of red mud has caused serious pollution. Through introducing the types and chemical composition of red mud, this paper summarizes the research progress of comprehensive utilization of red mud in the fields of extracting valuable metals, preparing new building materials and environmental protection. Because of the large output of red mud, the industrialization of red mud comprehensive utilization is the main research direction in the future.
